城市蔓延与服务业发展——基于城市面板数据的实证研究

Urban Sprawl and the Services Development: Based on City Panel Data

优化利用城市内部空间是新型城镇化的焦点。从财政分权和城市政府间竞争的角度建立城市空间蔓延模型,基于服务需求密度的模型突出城市蔓延对服务业发展的抑制作用。理论分析和基于城市数据的计量检验显示:城市政府拥有越高的财政分权、城市间竞争越激烈、交通基础设施越便利,城市空间蔓延就越快;城市空间快速蔓延、人口密度下降不利于服务业发展,尤其是抑制了消费性服务业的增长。

Optimizing allocation of the interior space of a city is the focus of new urbanization. The paper establishes a model of spread of urban space from the view of fiscal decentralization and competition of municipal governments,and the model of services development based on the service demand density to highlight the impact of urban spraw l. Theoretical analysis and empirical test on prefecture-level data show that the higher fiscal decentralization is,the more local competition among cities w ill be,the more convenient transportation infrastructure the city government gets,and the faster urban spraw ls. Then,the excessive urban spraw l and the reduction of population density are not conducive to the development of service industry,especially to consumer services grow th.
